Selected Answer: A

I dont agree with C. Because it is enough to query Id, since anyways the collection is a list of Sobjects. SO as long as we are querying the ID, it is enough to update any field in the record. So I don't believe this code will run into an error. SO for me the answer is A

i think A is correct as the query has a limit of 150 and the DML Limit is also 150

You can update fields without querying in SOQL (you can`t get the values from them without querying) So, A is correct

None of the answers are correct. Two interesting things: 1) you CAN update fields without querying in SOQL, but you can`t get the values from them without querying. 2) This snippet makes another error: System.LimitException: Too many SOQL queries: 101
